In addition to a nitrate-like action, nicorandil also functions as a potassium channel opener. Mechanism of Action: Theophylline has two distinct actions in the airways of patients with reversible obstruction; smooth muscle relaxation (i.e., bronchodilation) and suppression of the response of the airways to stimuli (i.e., non-bronchodilator prophylactic effects). Mechanism of action: . All cardiac glycosides are potent and highly selective inhibitors of active transport of Na + and K + across cell membranes. [, Goldschmidt M, Landzberg BR, Frishman WH: Nicorandil: a potassium channel opening drug for treatment of ischemic heart disease. Nitroglycerin is a vasodilator drug used for the treatment of chest pain and high blood pressure. Calcium overload in ischemic cells leads to impaired relaxation .

Some of their properties and actions are summarized, and their present applications and/or potential for . Nicorandil binds with ATP- sensitive potassium (KATP) channel and open them, causing potassium ions to leak from the cell. Careers. There are 2 types of SUR2 subunits (2A/2B) that have identical nucleotide binding domains (NBD), where SUR2A is more predominantly expressed in skeletal and cardiac myocytes and SUR2B in smooth muscle cells 2. It also facilitates release of NO leading to increased cGMP level, with reduction in intracellular calcium and vascular smooth muscle cell relaxation. These should settle as you get used to the tablets. Mechanism of action The sinoatrial node is the pace-maker of the heart. Similar to nitrovasodilators nicorandil predictably causes hypotension, headache (dilation of cerebral arteries), flushing .

Coronary arterial microvascular diameters were directly measured with fluorescence microangiography using an intravital microscope and stroboscopic epi-illumination . Nicorandil, a nicotinamide ester, is a vasodilator agent with a dual mechanism of action, which leads to relaxation of smooth tonic vascular muscles in both venous and arterial part of vessels. Mechanism of action: Cell membranes of smooth muscle cells have K+ channels. This hyperpolarizes the cell. 1987;10 Suppl 8:S109-15 It is metabolized in liver by de-nitration to form inactive N-(2-hydroxyethyl) nicotinamide, and reduction of the alkyl chain, leading to nicotinamide/nicotinic acid.

It acts as potassium channel activator and nitric oxide (NO) donor. KATP channel-dependent membrane hyperpolarization can also lead to vasodilation via reduction in Ca2+ influx through the voltage-gated Ca2+ channels and regulation of intracellular Ca2+ mobilization in smooth muscle cells 6. In addition, the limited data available indicate that nicorandil may be effective in patients with unstable and variant angina who are refractory to therapy with conventional antianginal agents, a potentially important area for further study.
